This invention relates to a window sash and more particularly tostrips'for securing panes of glass in window sashes, it being one objectof the invention to provide strips bymeans of which the window panes maybe firmly held in place and easily removed when they become broken andhave tohereplaced.

Anotherobject of the invention is to provide .strips of suchconstruction that they may he applied to edge portions of a :pane ofglass with-the said edge portions of the pane disposed between the .jawswhich are held in gripping engagement with the inner and outer faces ofthe pane by screws which serve to secure the strips firmly in placeagainst a window sash.

Another object of the invention is to provide strips in which aremounted packing strips which are formed of soft rubber and permitexpansion and contraction of the glass pane in response to heat and coldand thus prevent the glass panes from being cracked by expansion.

Another object of the invention is to provide strips of suchconstruction that they maybe each formed from a single sheet metalblank, certain of the strips being formed with openings with whichopenings formed through packing strips reg'isterso that air may flowthrough the registering openings into and out of space 'between'innerand outer panes of a storm window and provide a'goo'd heat insulationfor the window sash.

Another object of the invention is .to provide securing strips which aresimple in construction and capable of being manufactured at low cost.

The invention "is illustrated in the accompanying drawings wherein:

Fig. 7 is a vertical sectional view of the transom of a window showing amodified strip securing an inner pane to the sash.

Fig. 8 is a vertical sectional view of a top bar 2 of a window sashshowing a further modified strip securing an inner pane to the sash.

The window sash which is indicated in general .by the numeral 1 consistsof the usual side rails and upper and lower crossrails. A portion of alower sash ,2 has been shownin Figure l and it willbe understood thateach sash is provided with inner and outer glass panes 3, and 4 whichare held in place by strips of the improved construction. These stripsare mounted along inner margins of the side rails and upper andlowerrails and each has inner and outer jaws between which marginal portionsof the pane are disposed so that when screws 5 are applied and tightenedto secure the strips to the sash the pane will be gripped between thejaws and firmly held in place. The sash in Figure .1 has been shownprovided with inner and outer paneswhich are spaced from each other toform .a storm window. but it will be understood that the sash may beprovided with a single pane if so, desired.

The strips shown in Figure .l are each formed as shown .iniFigure 2, andreferring to this figure it will Joe. seen that the securing strip is.formed from an elongated stripof sheet metal, .or other suitablematerial, which is bent intermediate its width to form leaves 6 and l.The leaf 1 is .diS- posed in diverging relation to leaf .6 and is fiatthroughout its width except .Ior its free ed e portion which is bentinwardly at incline to .form .a lip .8 extending its full length. Theleaf 6 extends in diverging relation to leaf 1 for approximatelyone-half the width thereof and is then Sbent outwardly to form alaterally extendingledge .9 from which projects a flange II] having itsfree side edge portion bent to form a lip H disposed opposite the hp 8.The ledge 9 forms the side wall of a pocket having .inner and outerwalls formed by the flange I10 and the free side portion of the leaf 7|projecting beyond ledge '9. vOp positely disposed openings v1Z2 are,iormed in the lleavesii and! to receive thescrews '5, and from aninspection of Figure 1 it will be seen that when the screws 5 are passedthrough these openings and .into the sash .l and tightened the leaf 1will "beio'rced towards leaf 6 until the pane of glass is grippedbetween the lips 8 and 1] of the inner and outer side walls which may bereferred to as pane-engaging jaws. Therefore the screws serve to holdthe jaws in gripping engagement with the glass pane :as well as servingto secure the strip against the sash. The leaf 6 may have directengagement with the surface of the sash, as shown at the left of Figure1, or a strip of rubber l3 may be fitted between the sash and the leaf6, as shown at the right of this figure, and serve as a packing orcushion for the strip and prevent cold air or rain water from leakinginwardly between the strips and the side rails and cross rails of thesash.

Edge faces of the glass pane are engaged with thick rubber strips orpacking l4 fitted into the strips between the flanges ll] of theirleaves 6 and opposed portions of the leaves I and serve as cushions forthe glass pane and also as sealing strips.

These packing strips I4 may be solid for their entire length or they maybe formed with bores or openings [5 which register with openings 16formed in the leaves of the strips and thus form air passages whichcommunicate with space I! between the inner and outer panes 3 and 4. Ifth packing strips are solid dead air spaces will be formed between theglass panes and if the sealing strips of the inner or outer pane areformed with the openings air will be allowed to flow through them andthus keep the space filled with live air. If so desired openings IS inthe flange l may be omitted and notches I I formed in the lip I l toinsure an air passage.

In Figure 3 there has been illustrated a securing strip of modifiedformation. This strip is in most respects of the same construction asthat shown in Figures 1 and 2 and corresponding parts have beenindicated by the same reference numbers. It will be noted, however, thatthe openings l6 are omitted and solid packing strips are fitted intothis type of securing strip. In order that air may fiow into and out ofspace between inner and outer window panes this form of strip has itsleaf I formed with a suitable number of channels l8 which are spacedfrom each other longitudinally thereof and have open inner and outerends, the inner ends communicating with slots 0r recesses I9 formedacross interconnected inner side edges of the two leaves 6 and 1 andouter ends of the channels opening through the junction of the leaf withits lip 8. This form of strip is mounted against a sash the same as thatshown in Figure 1 and air flows through the channels I8,into and out Ofspace between the window panes.

Fig. shows a pane securing strip which is similar to that shown inFigures 2 and 3 but is applied to'the window sash with its leaf 1disposed towards the side face of the sash instead of having the leaf 6confronting the sash and its ledge 9 projecting into the pane-receivinopening of the sash. The leaf 1 may hav direct engagement with the sashor a strip of rubber may be disposed between this leaf and the sash andform a tight joint. Openings 2! are formed through the rubber strip M inalignment with openings 22 and 23 formed in the lip 8 and at connectedside edges of the two leaves and cooperate therewith to form airpassages so that air may flow through the securing strip into and out ofspace between inner and outer panes of the sash,

Figure 4 shows a pane securing a strip which is applied in a mannerdifferent from the strips shown in Figures 1 and 5. In this embodimentof the invention the leaves 24 and 25 are bent to form laterallyextending portions 26 and 21 which are in their turn bent to formflanges 28 and 29 terminating in diagonally disposed lips 30 and 3|.

The flanges 28 and 29 and the portion of the section 21 of leaf 25extending between them cooperate with each other to form apane-receiving socket in which the sealing strip 32 is fitted. When thisform of securing strip is in use the leaf 25 and its laterally extendingportion 21 are fitted to the sash, as shown, and the screws 5 passedthrough aligned openings in the leaves. When the screws are tightenedthe leaf 24 is forced "towards leaf 25 and this causes the flange orwall 26 to be moved towards the flange or wall 29, thus causing theglass pane to be gripped between the lips 30 and 3|.

The securing strip shown in Figure 6 is also formed of sheet metal andhas leaves 33 and 34 which are formed with openings 35 to receive thescrews 5. The leaves 33 and 34 are shorter than the leaves 24 and 25 andare bent to form flanges 36 and 31 which correspond to the flanges orwalls 28 and 29 and have diagonally extending lips 38 and 39 along theirfree side edges for gripping the glass window pane which fits into thesocket, formed by the flanges 36 and 31 and the portion of the leaf 34projecting beyond the flange 36, and rests against the elastic strip 40.The window sash may have a single glass pane secured by strips of theconstruction shown in Figure 6 or as shown in Figure 4 or Figure 5 ortwo panes may be used with one secured as shown in Figure 6 and theother as shown in Figure 5 to form a storm sash.

Having thus described the invention, what is claimed is:

A window pane fastener comprising an elongated strip folded transverselyand forming leaves upwardly diverging toward their free side edges andformed with opposed openings through which screws are adapted to bepassed to secure the strip against a window sash and force the leavestoward each other to a window pane securing position, one of said leaveshaving a portion bent outwardly at right angle to form a laterallyextending ledge adapted to be supported by the inner face of a windowsash and carry the weight of a glass and thence bent upwardly andtogether with the companion leaf defining jaws and a. pocket between thejaws, an elastic packing strip extending longitudinally in said pocketin position for engagement with the edge face of a marginal portion of awindow pane fitted into the pocket, diagonal lips along free side edgesof said leaves and extending towards each other in position for grippingopposite inner and outer faces of the window pane when the screws aretightened, per-' forations in the jaws of the pocket, and transverselyextending openings in the packing strip and registering with theperforations and constituting air vents.
